Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A European style double-folded combined cover is shown in figures 1-8, an outer cover 1, a rubber plug 2 and an inner cover 3, wherein the outer cover 1 comprises an outer cover body 11, two independent rubber plug cavities 12 are convexly arranged at the top of the outer cover body 11, medicine holes 13 are respectively arranged at the tops of the two rubber plug cavities 12, and the medicine holes 13 are sealed 14 through independently arranged easy-to-fold handles; the rubber plug 2 is arranged in the rubber plug cavity 12, and the flange 15 is arranged on the inner top surface of the outer cover body 11 around the rubber plug cavity; the inner cover 2 is provided with a through hole corresponding to the position of the medicine hole 13, and when the infusion needle is inserted, the inner cover does not need to be punctured. The inner cup 3 sets up in enclosing cover body 11 to the lock is in the bottom in plug chamber 12, in order to inject plug 2 in plug chamber 12. Wherein, the inner cover 2 is connected with the outer cover body 11 through an ultrasonic welding machine; specifically, the flange 15 and the inner lid 3 are fusion-fixed by ultrasonic welding. The protruding reference column 31 of establishing of upper surface of inner cup 3, the interior top surface of enclosing cover body 11 sets up and reference column 31 complex constant head tank 16 to cooperate through constant head tank 16 and reference column 31, confirm the 3 mounted position of inner cup, and can restrict inner cup horizontal migration, make inner cup 3 and enclosing cover body 11 become overall structure.

In one embodiment, as shown in fig. 1-8, the positioning post 31 is a truncated cone, and correspondingly, the positioning slot 16 is also a truncated cone structure, so that the positioning post 31 can be inserted into the positioning slot 16 conveniently.

In one embodiment, as shown in fig. 1 to 8, there are two positioning slots 16, and the two positioning slots 16 are respectively disposed between the two rubber plug chambers 12 at intervals.

In one embodiment, as shown in fig. 1 to 8, the inner surface of the outer cap body 11 is recessed with a fitting groove 17, the inner cap 3 is mounted in the fitting groove 17, and a gap is provided between the outer wall of the inner cap 3 and the inner wall of the fitting groove 17. When inner cup 3 and enclosing cover body 11 passed through ultrasonic bonding welding, flange 15 melting spills over to both sides, through at including between lid 3 and enclosing cover body 11 reserve the clearance, avoids flange 15 after the melting to spill over to inner cup 3 surface, increases the post processing step.

In one embodiment, as shown in fig. 1-8, the rubber plug 2 is cylindrical, and the sidewall of the rubber plug 2 is circular arc. The rubber plug 2 is tightly matched with the rubber plug cavity 12, and the side wall of the rubber plug 2 is arranged to be of an arc structure, so that the rubber plug 2 can be conveniently plugged into the rubber plug cavity 12.

In an embodiment, as shown in fig. 1 to 8, the upper surface and the lower surface of the rubber plug 2 are respectively provided with a sealing groove 21 in a concave manner, the rubber plug cavity 12 and the inner cover 3 are provided with a sealing rib 4 matched with the sealing groove 21, and during assembly, the top of the sealing rib 4 is tightly attached to the bottom of the sealing groove 21, so that the sealing rib 4 and the rubber plug 2 are sealed.

In one embodiment, as shown in fig. 1 to 8, the cross section of the sealing groove 21 is trapezoidal, and the cross section of the sealing rib 4 is trapezoidal. Preferably, a gap is provided between the sidewall of the seal rib 4 and the sidewall of the seal groove 21. Because of inner cup 3 is fixed through ultrasonic welder with enclosing cover body 11, consequently, inevitable meeting production friction between sealed muscle 4 and the seal groove 21 can make sealed muscle 4 melting, through setting up the clearance between the lateral wall at sealed muscle 4 and the lateral wall of seal groove 21, reduces sealed muscle 4 and seal groove 21 area of contact, reduces sealed muscle melting volume, and fused welding muscle 4 overflows to the clearance in simultaneously, avoids overflowing to the surface.

In one embodiment, as shown in FIGS. 1-8, the frangible stems 14 are integrally formed with the outer cap body 11.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
